The Spaniard came under fire after bringing down Red Devils winger Daniel James during the first period, leaving Marcus Rashford with the honour of giving their opponents the lead.
Despite Michy Batshuayi scoring in the second half to bring Chelsea level, they couldn’t hold on as Rashford found the net from 35 yards to ensure that United went into the last eight of the competition.
Alonso was active on Chelsea’s left-hand side and whipped in some testing crosses but was accused of being clumsy when challenging James.
Supporters were furious with his challenge and were quick to voice their views on social media. One fan believed that Alonso is the worst player he’s ever seen, while another believes it is “tragic” that people think that the Spaniard is a footballer.
Here are some harsh words for Alonso here:
I stand by this, Marcos Alonso is the worst player I’ve ever seen.
